Hi im stuck on a homework problem and wanted to see if anyone can help me.

The current stock price of a company is $54.50, the continuous annual standard deviation was 53.00%, the exercise price of an European call on the stock is $58.00, the exercise price of an European put on the stock is $58.00, the time to maturity for both options is 0.43 years, and the yield on a risk-free Treasury Bill maturity on the same date at the options is 6.72%. Determine the current prices of the call and put.

I know how to solve for the call and put price, but where I got lost was the standard deviation. I've never had to do a problem like this using the deviation. If anyone can help i would really appreciate it.

Hey so I'm also a student so I don't really know but the standard deviation is telling you that the stock moves up or down by 53% per year. but you have to find the price at 0.43 years...maybe there is something in the "the continuous annual standard deviation" thing. I don't know if that bit of insight helps...
